CONNECT VT1OO TERMINAL TO NMIC RS232 PORT
AND MODIFY NMIC IP ADDRESS
Summary: This procedure describes making the connection from a VT100 terminal (or PC with VT emulating software) to the NMIC RS232 port, and setting the IP address. The craft connector wiring convention is also covered in this DLP. The NMIC craft port is only used during initial setup of the NMIC to initialize the environment and enable Graphical User Interface (GUI) or Simple Network Management Protocol (SNMP) capabilities from a Network Management System (NMS). The IP is the target address for NMS access to the system information. The IP address should be assigned by the Network Engineer and programmed into the Cellworx STN by the user.
The NMICs are a PowerPC workstation running Linux software and are shipped with a temporary physical IP address of 155.226.39.28 which may be used to initially communicate with the NMIC. The USER however must modify the IP address before using the Cellworx system. A brief overview of the IP Address implementation in Cellworx, the process of changing the IP address, and the process of displaying the Cellworx Graphical User Interface is described in this procedure. If the NMIC status LED is blinking red, the network information has not yet been configured.
If the IP addresses are not listed in the installation work order or project book, consult with your company’s corporate Networking Administration for policies and acquisition of suitable IP addresses. Companies can create their own IP networks without any relationship to the public IP network. This may be desirable since the STN would be set on a private IP network and not on the public IP network. If these IP addresses are never intended to communicate with the outside world, the assignment of an IP address is arbitrary. For sanity reasons, pick an address using the following blocks that are specified as "internal network".
•10.0.0.0 to 10.255.255.255
•172.16.0.0 to 172.31.255.255
•192.168.0.0 to 192.168.255.255, (except 192.168.88.0 and 192.168.90.0 which are internal to the ring system. Refer to the /etc/hosts file for listings)
Note: This procedure assumes the NMIC is installed in the correct slots within the GNE shelf and has power applied.
Caution: Modules can be damaged by static electrical discharge. Before handling any modules connect your wrist to an equipment ground using an approved
1.Obtain access to a VT100 terminal, or a PC with VT emulation software, at GNE location. Verify the connector pin out per the NMIC Craft port pin out information shown in Figure
